Filed SGTXT in table BSEG is not updating

Hi all,

We done upgrading from 4.6C to ECC6.0. We have an issue regarding bseg-sgtxt.

When we run report FBL1N, we found Item text ( SGTXT ) is missing. Which was there before upgrade. This text is coming from table BSEG.

Can anyone give me an idea how this field is updating in table BSEG. And, why was it working before upgrading (4.6c) ????

Are there any userexits missing?

Thanks
